THIS HARNESS IS ONLY FOR VEHICLES NOT EQUIPPED WITH THE SEAT BELT INTERLOCK SYSTEM.

This system prevents a vehicle from starting unless the seat belts are fastened. The seat belts must be fastened within a specific sequence. The driver (and front seat passenger) must get into the car, close the door(s), and then fasten the seat belts. If the seat belts are not fastened, or if they are fastened in an incorrect order, the car will not start.

All 1974, and early-to-mid 1975 vehicles had the seat belt interlock system.

We suggest trying to locate the specific components of the interlock system within the vehicle to confirm if your car is equipped with the seat belt interlock system.

Please Note: There are no returns on electrical items.
